Abstract
La présente invention comporte une cellule d'électrolyse configurée pour retenir un bain d'électrolyte fondu, le bain comprenant au moins un composant de bain, la cellule d'électrolyse comprenant : une partie inférieure et une paroi latérale se composant essentiellement d'au moins un composant de bain ; et un système d'alimentation configuré pour fournir un matériau d'alimentation comprenant le ou les composants de bain, au bain d'électrolyte fondu de telle sorte que le ou les composants de bain présentent 2 % de saturation. Par l'intermédiaire du matériau d'alimentation, la paroi latérale est stable dans le bain d'électrolyte fondu.
